<h1>
TIL KINGDOM COME
</h1>
<p class="p1">
One... two... <br>
Steal my heart... and hold my tongue <br>
I feel my time... my time has come <br>
Let me in... unlock the door <br>
I never felt this way before <br>
And the wheels just keep on turning <br>
The drummer begins to drum <br>
I don't know which way I'm going <br>
I don't know which way I've come <br>
Hold my head... inside your hands<br>
I need someone... who understands<br>
I need someone... someone who hears<br>
For you I've waited all these years<br>
For you I'd wait... 'Til Kingdom Come<br>
Until my day... my day is done<br>
and say you'll come... and set me free<br>
just say you'll wait... you'll wait for me<br>
In your tears... and in your blood<br>
In your fire... and in your flood<br>
I hear you laugh... I heard you sing<br>
I wouldn't change a single thing<br>
And the wheels just keep on turning<br>
The drummers begin to drum<br>
I don't know which way I'm going<br>
I don't know what I've become<br>
For you I'd wait... 'Til kingdom come<br>
Until my days... my days are done<br>
Say you'll come... and set me free<br>
Just say you'll wait... you'll wait for me<br>
Just say you'll wait... you'll wait for me<br>
Just say you'll wait... you'll wait for me<br>
